Detailed description of the invention
The present embodiment is this utility model preferred implementation, and other its principles all are identical with the present embodiment with basic structure
Or approximation, all within this utility model protection domain.
Refer to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, in this utility model, reinforcement steel disc mainly includes steel disc body 1 and thermosetting
Glue 2, together with hot-setting adhesive 2 is fixedly installed with steel disc body 1, hot-setting adhesive 2 is recessed in reinforcement steel disc body 0.15～0.3mm, i.e.
The outer edge 0.15～0.3mm of the outer edge distance steel disc body 1 of hot-setting adhesive 2, it can effectively ensure reinforcement steel disc and FPC
Between bonding strength, can effectively solve again the hot-setting adhesive 2 excessive glue problem in hot pressing.In the present embodiment, at steel disc
Offer fabrication hole 3 on body 1, around fabrication hole 3, also be provided with hot-setting adhesive 2, outside the outer edge distance fabrication hole 3 of hot-setting adhesive 2
Edge is also 0.15～0.3mm.
Refer to accompanying drawing 4, this utility model protects a Seed packaged band simultaneously, and it stamps out single steel disc body 1 on steel band
Being formed, material strip includes the single steel disc body 1 of more than material strip support part 4 and a row, and in the present embodiment, steel disc body 1 sets
There are two rows, material strip support part 4 to be respectively provided on two sides with hole 5, location, each steel disc body 1 is provided with hole 5, a location.
Manufacturing process of the present utility model comprises the steps:
1, design hot-setting adhesive and reinforcement steel disc, owing to bi-material is required to design size, arrangement etc., design sequence regardless of
Successively:
A, hot-setting adhesive design: with reinforcement steel disc a size of radix, hot-setting adhesive be recessed in reinforcement steel disc body 0.15～
0.3mm；
B, reinforcement steel disc design: carry out typesetting according to reinforcement steel disc size, and during typesetting, necessary related positioning process hole 5 is together
Design typesetting, meanwhile, carries out punching mold part design according to typesetting, carries out punching mold part design according to typesetting, location
Fabrication hole 5 designs in steel band scrap area (i.e. material strip support part 4), for gummed paper location and the location of second time punching press；
2, hot-setting adhesive carries out wall scroll design with reference to reinforcement steel disc typesetting, makees with the positioning process hole 5 on reinforcement steel disc material strip
For positioning datum.In order to ensure machining accuracy, wall scroll gummed paper length uses cutting die cross cutting or five metals at about 150mm, gummed paper
Stamping die punching press production method makes；
3, use high velocity ram machine (punching speed 300 times/min of ＞) that steel band carries out punch process, for the first time punching press bag for the first time
Containing the positioning process hole 5 on material strip and fabrication hole 3 punch forming together on product；
4, making localization tool, localization tool uses aluminium sheet or bakelite plate material to make.Positioning needle on tool should exceed
Tool face about 3-5mm, positions the steel band after first time punching press and the wall scroll hot-setting adhesive after cross cutting for borehole jack and enters tool positioning needle,
Use flatiron pressing hot-setting adhesive after pressing, allow it be pasted on the steel band after for the first time punching press；
